EXfiIBIT D - MINING PLAN <br />Preliminary exploration drilling has outlined several <br />ore horizons spread throughout the lease area at various <br />depths. To mine these ore horizons from one entryway, a <br />decline is being driven 1800 feet at 15.596 from the hori- <br />zontal. As of August 31, 1977 this decline has advanced <br />a slope distance of 1400 feet and is expected to bottom out <br />by the end of October 1977. The entryway is 9 feet high <br />by 11 feet wide inside of timber and will be driven by <br />conventional drill-blast techniques. The mobile rock <br />moving equipment will be 2 yard front end loaders and 10 <br />ton trucks which are diesel powered and rubber tired. <br />Rock-support will be provided-by conventional timbering <br />and rock bolting"in conjunction with shot-Crete. <br />• After the incline is complete, the underground station <br />is installed, and a ventilation raise is upreamed, develop- <br />ment drifting will commence toward the ore horizons. The <br />direction and grade of the drifts are shown on the develop= <br />went map, along with the projected yearly completion <br />schedule. These development drifts are to be driven with the <br />same equipment and techniques used in sinking the decline. <br />When drift development has progressed past stoping areas, <br />stope development and mining will begin. A~modified room and <br />pillar stoping method will be used to mine the ore. This <br />stoping method is similar to the one presently used in the <br />Uravan Mineral Belt, i.e. split shooting is used in con~unc- <br />. tion with leaving waste pillars and ore pillars wherever <br />necessary for roof support. The equipment and methods des- <br />cribed in the development phase will be utilized in the <br />mining phase. <br />i <br />
